Detailed instructions:
1. using HC-06 slave module, core module, which leads to the interface includes VCC,GND,TXD, RXD, reserved LED state output pin, MCU can state whether the bluetooth is connected through the foot, slave KEY pin is invalid
2. the led indicator bluetooth connection status, twinkle said there was no bluetooth connectivity, Chang Liang says the bluetooth is connected and turned on the port
3. plate set meter diode with 3.3V ", as the input voltage 3.6~6V, unpaired current about 30 ma, matching after about 10mA, no more than 7V input voltage!
4. interface level 3.3V, can be connected directly to all kinds of single chip microcomputer (51, AVR, PIC, ARM, MSP430, etc.), 5V single chip can be connected directly, without MAX232 couldn't through MAX232.
5. clearing the effective distance of 10 meters (power rating is CLASS 2), more than 10 meters is possible, but I don't have distance connection quality
6. after matching when full duplex serial port to use, do not need to know any bluetooth protocol, but supports only one in the eight data bits, stop bits and parity checking the communication format, which is the most commonly used communication format, does not support other formats.
7. when the bluetooth connection has not been established support by pairing the AT command set baud rate, name, password, set the parameters of the power save. After the bluetooth connection automatically switch to passthrough mode
8. small size (3.57cm*1.52cm), SMT factory, ensure the quality of the patch. And set transparent heat shrinkable tube, dust and beautiful, and there are some antistatic ability.
9. the link is slave, slave and all kinds of computer with bluetooth function, the bluetooth host, most with a bluetooth mobile phone, PDA, PSP and other intelligent terminal matching, between the slave can not match.
